Specification of Letters Xate'nt. Patgntgd N 39, 1909,

Application filed March 9, 1909. Serial No. 482,319.

To all whom it may concern."

Be it known that I, ALEXANDER Swamson, a citizen of the United States, residing at Spokane, in the countyof bpokane and State of lVashington, have invented certain new and useful Improvements in Insect-Destroyers, of which the following is a specification.

This invention relates to that class of plant insect destroyers in which the insects are knocked oft the plants by a rotary brush or agitator, and precipitated into a receptacle in which the are destroyed by burning; and the object o" the present invention is to improve and simplify the general structure of the machine, and also to render the machine more efficient in operation.

Nith the foregoing-objects in View, the invention consists in a novel construction arts to be hereinafter described and claime reference being had to the drawing hereto annexed forming a part of this specification, in which drawing,

Figure 1 is a transverse 'section of the machine. Fig. 2 is a longitudinal section.

The frame of the machine includes an axle 5 supported on wheels (3, and carrying spaced longitudinal side beams 7, and an inter.- mediate longitudinal beam 8, the latter beam extending forwardly sufiiciently to form a tongue 9 forattachment of the draft animals. The beams 7 and 8 are connected by transverse front and rear beams 10. A seat'll is mounted on the beam 8, and said beam also suppqrtsan oil tank or receptacle l2.

From the beams 10, adjacent to the ends thereof, depend hangers 13 carrying the insect receiving pans 14. The hangers are secured to the beams by straps 14L fastened to the latter, and pins 15 passing through openings in said straps, and in the hangers and beams. A numberof openings 16 are made in the hangers, in order that they may be adjusted vertically, and. the pans thus raised or lowered to suit the height of the plants to be operated on. The pans are supported at each of their ends by these hangers, and diagonal braces 17 are connected to the hangers and the ends of the pans, whereby a strong and rigid support for the latter is had. -The pans are also connected at their.front ends by chains 18 to'the tongue 9, and said ends are pointed as clearly shown in Fig. 2 in order that they may'more readily clear weeds or other obstructions. At I the inner longitudinal edges of the pans are outwardly and, downwardly curved lips 19 I which extend close to the plants on opposi i sides thereof, beneath the foliage, and ser as a guard to prevent the insects from dropping betwe'cn the plants and the pans, and thus escaping. By making the lips curved, no sharp edges are presented to the plants, and they are therefore not liable to be damaged if they are struck by the lips. In the pans are burners comprising pipes 20 which are supported on the bottom of said pans, and extend throughout the entire length thereof. The pipes have suitable burner openings, and also contain a wick 21. Pipes 22 extending from the tank 12' to the pipes 20, carry the oil or other fuel to the latter. The pipes 22 are fitted with valves 23 for controlling the flow of oil to the burners. Each pan covered by a screen 24 located above the burners, and inclined in the direction of the center of the pans.

At 25 is indicated a rotary brush or agita for knocking the insects oil the plants an into the screens 24. The brush is locatei at, and hasits axis parallel to the iongitudinal middle of the machine. The brush shaft is supported in bearing brackets 26 secured to and depending from the beam 10. The following gearing is employed whereby the brush is driven by the wheels (3 of the machine: On the axle 5 is a bevel gear 27 which meshes with a similar gear-28 on a .shaft 29 supported in suitable bearings 30 the same being directly over the burners,

and they are thus consumed or killed. By mchning the screens in the direction of the burners, ,the destruction of the insects is as sured. The screens also prevent the insects from collecting around the burners and thus clogging the same. A screen til is also provided for the outer longitudinal edges of the pans to prevent the brush from throwing the insects too far.

I claim:

1. In an insect destroyer, :1 wheeled supagitator on opposite sides thereof, burners in 'agitator on opposite sides thereof, b'urners in direction of the burners.

porting frame, a Wheel-driven rotary agitater carried thereby, pans located below the thepans, and screens over the pans above the burners, SfllCl screens being inchned 1n the the pans, and screens over the burners, said screens being downwardly inclined from 0pposite edges of the pans in the direction of the burners, and the latter being located beneath the lowest portions of the screens.

In testimony whereof l-afiix my signature in presence of two Witnesses.

ALEXANDER SWAINSON.
